Abstract
Description
본 발명은 윤활성이 우수한 절연전선에 관한 것이다.The present invention relates to an insulated wire excellent in lubricity.
근년 절연전선을 사용하는 전기 메이커 등에서는 기기의 제조 공정의 신속화를 도모하기 위하여 고속 자동 권선기를 사용하고 있다. 그러나 이 경우에 공정의 신속화에 의하여 기기의 가공비는 현저히 감소되는것처럼, 보였으나 실제로는 권선 가공시 절연전선은 마찰등으로 절연층이 기계적 손상을 받아 이로인해 기기에 내장된 후 레이쇼오트가 발생하여 로스율이 대폭적으로 증가되는 큰 문제가 있다. 이것을 해결하기 위하여 절연전선에 윤활성을 부여하고, 기계적 손상을 저감하는 것이 시도되고 있다. 이것은 자등 권선기뿐만 아니라 수동작업에 있어서도 동일하고, 예를들면 모우터의 좁은 슬롯에 절연전선을 삽입할때 수등작업의 능률을 높이기 위하여 활성이 좋은 절연전선이 요망된다. 절연전선자체는 윤활성이 빈약하기 때문에 절연전선끼리, 절연전선과 권선기 사이, 절연전선과 기기 사이의 활성이 나빠서 절연층에 손상을 받거나 작업효율이 저하한다. 이를 위해 절연전선상에 유동파라핀, 냉동기유 등의 액체의 윤활제를 도포하는 방법이 취해지고있다. 그러나 이 방법은 윤활성, 활성이 불충분하기 때문에 수동작업에서 선의 조작성이 좋지않고, 또 권선시에는 트랜스, 코일등의 권선의 정렬성이 좋지못한 난점이 있고, 또 근년의 고속권선화, 점적률 향상 인서어터 방식의 적용확대 등에 의하여 융착이 불충분해지거나 레어쇼오트가 증대되고 있다. 윤활성을 향상시키려고 다량의 액체윤활제를 도포해도 그 효과는 거의 없고, 오히려 전선에 먼지가 부착해서 코일의 단말처리를 위한 접착테이프의 접착력에 악영향을 주어 테이프가 박리되는 결점도 있다. 한편 액체의 윤활제보다도 윤활성이 강한 고형파라핀, 카아나바납등의 고체 윤활제를 절연전선에 , 도포하는 것이 시도되고 있다. 고체 윤활제를 절연전선상에 균일하게 도포해야 하므로 통상 석유벤진, 톨루엔, 키실렌등의 용제에 윤활제를 수% 용해시킨 용액이 사용된다. 따라서 이 방법은 다량의 저비점용제를 사용하기 때문에 안전위생상 좋지 아니할 뿐만 아니라 전선품종에 따라서는 용제에 의하여 크레이징을 발생하여 전선으로서 상품가치가 없어지기 때문에 적용품종이 한정되는 문제가 있다. 또, 이들 고체의 윤활제를 도포한 절연전선을 냉동기용 모우터등에 적용하면 냉매에 의해서 추출되는 윤활제가 콤프레서의 밸브나, 팽창기내의 냉매 분출노즐등에서 막혀서 냉동능력이 저하되는 염려가 있다. 또 윤활제가 냉매에 추출되어 버리면 절연전선자체의 윤활성이 나빠져서 전자(電磁)진등 등으로 절연전선의 피막은 손상을 받기 쉬워지는 결점도 있다.In recent years, electric makers using insulated wires have used high-speed automatic winding machines to speed up the manufacturing process of equipment. In this case, however, the processing cost of the equipment seemed to be significantly reduced by the rapid process, but in practice, the insulation wire is mechanically damaged due to friction due to friction, etc. There is a big problem that the loss rate is significantly increased. In order to solve this problem, it has been attempted to impart lubricity to the insulated wire and to reduce mechanical damage. This is the same for manual winding as well as magnetic winding machine. For example, when inserting an insulated wire into a narrow slot of a motor, an active insulated wire is required to increase the efficiency of the hand work. Since the insulated wire itself has poor lubricity, activity between the insulated wires, between the insulated wire and the winding machine, between the insulated wire and the device is poor, and the insulation layer is damaged or the work efficiency is reduced. To this end, a method of applying a lubricant of liquid, such as liquid paraffin and refrigeration oil, has been taken on an insulated wire. However, this method has insufficient lubricity and activity, and thus the operation of wires is poor in manual operation, and the windings have poor alignment, such as transformers and coils. Due to the expansion of the application of the inserter method, fusion is inadequate or rare shots are increasing. Even if a large amount of liquid lubricant is applied to improve the lubricity, the effect is almost insignificant. On the contrary, dust adheres to the electric wires, which adversely affects the adhesive force of the adhesive tape for the termination of the coil, thereby causing the tape to peel off. On the other hand, it has been attempted to apply solid lubricants, such as solid paraffin and caranaba nap, which are more lubricious than liquid lubricants, to insulated wires. Since a solid lubricant must be uniformly applied on the insulated wire, a solution in which a few percent of the lubricant is dissolved in a solvent such as petroleum benzine, toluene, and xylene is usually used. Therefore, this method uses a large amount of low boiling point solvent, which is not good for safety hygiene, and depending on the cable type, there is a problem in that the applied type is limited because the product value is lost due to the crazing caused by the solvent. When the insulated wire coated with these solid lubricants is applied to a refrigerator motor or the like, there is a fear that the lubricant extracted by the refrigerant is blocked by the compressor valve, the refrigerant ejecting nozzle in the expander, and the like, and the freezing capacity is lowered. In addition, when the lubricant is extracted to the refrigerant, the lubricity of the insulated wire itself is deteriorated, and the coating of the insulated wire is susceptible to damage due to electromagnetic vibration or the like.
절연전선에 윤활성을 부여하는 방법으로는 다시 절연전선용의 절연도료 속에 미리 폴리에틸렌, 폴리프로필렌,4불소화에틸렌수지 등의 윤활성이 용수한 합성수지나 실리콘우, 불소계계면활성제, 파리핀왁스, 카아나바납, 몇탄납 등의 액체. 고체의 각종 윤활제를 첨가해 놓는 방법이 제안되고 있다. 그러나 이 방법에서 폴리에틸렌, 폴리프로필렌, 4불 소화에틸렌수지 등의 합성수지의 경우는 이들 합성수지가 절연전선용의 절연도료의 용제에 난용이기 때문에 도료속에 균일하게 분산하기가 어렵고 또 도료의 안정성도 나쁜 결점이 있을뿐만 아니라 절연재료와 상용성이 없기 때문에 절연피막중에 균일하게 분산되기가 어렵고, 또 미관이 나빠지는 문제도 있다. 또 액체의 윤활제를 첨가할 경우는 절연전선상에 도포하는 경우와 같이 활성, 윤활성이 불충분하다. 또 고체의 윤활지를 첨가하는 경우에 있어서는 절연전선상에 도포하는 경우와 같이 냉매나 용제에 의해서 윤활제가 추출되는 일이 없고 냉동기 모우터용의 절연전선 등에의 적용이 곤란해지는 뿐만아니라 합성수지를 첨가할 경우와 같이 고체의 윤활제는 절연전선용의 용제에 난용이ニ, 또 절연전선용의 절연재료와도 상용성이 없기 때문에 도료의 안정성이 좋지 못하고 또 절연피막속에 균일하게 분산되기가 어렵고, 외관이 나빠지는 결점도 있다.In order to provide lubricity to the insulated wire, synthetic resin, silicone milk, fluorine-based surfactants, paraffin wax, and carnauba wax in which lubricity such as polyethylene, polypropylene, and tetrafluoroethylene resin were previously dissolved in the insulating paint for the insulated wire again. , How many lead and other liquids. A method of adding various kinds of solid lubricants has been proposed. However, in this method, in case of synthetic resins such as polyethylene, polypropylene, tetrafluoroethylene, etc., these synthetic resins are difficult to disperse uniformly in the paint because they are difficult to dissolve in the paint of the insulating wire for insulated wire and the stability of the paint is also poor. In addition to this, there is also a problem that it is difficult to be uniformly dispersed in the insulating film and the appearance is poor because it is not compatible with the insulating material. When a liquid lubricant is added, the activity and lubricity are insufficient as in the case of coating on an insulated wire. In addition, when adding a solid lubrication paper, the lubricant is not extracted by a refrigerant or a solvent as in the case of coating on an insulated wire, and it is difficult to apply to an insulated wire for a refrigerator motor or the like and to add a synthetic resin. As such, solid lubricants are poorly soluble in solvents for insulated wires and are not compatible with insulators for insulated wires, resulting in poor paint stability and difficulty in uniformly dispersing them in the insulator coating. Also has its drawbacks.
본 발명자 등은 이러한 문제를 해걸하기 위하여 예의 검토한 결과 본 발명을 완성한 것이다.MEANS TO SOLVE THE PROBLEM The present inventors completed this invention as a result of earnestly examining in order to solve such a problem.
본 발명은 절연도료를 도체상에 직접 또는 다른 절연물을 개제하여 도포. 열처리해서 얻어지는 절연전선에 있어서 적어도 한개의 분자의 말단이 탄소수 21이상의 알칼리기인 폴리 아미드수지를 주성분으로 하는 드로틀 적어도 최외층에 도포. 열치리해서 언어지는 절연전선이다. 절연전선상에 고형 파라핀, 카이나바납과 같은 고체 윤횔제를 도포할 경우, 또 이들 고체 윤활제나 폴리에틸렌, 폴리프로필렌 등의 윤활성이 우수한 합성수지를 절연도료에 첨가허서 절연전선을 얻는 경우와 비교해서 본 발명의 절연전선은 그 자체에서 동등의 윤활성을 갖는다.The present invention is applied to the insulating paint directly on the conductor or other insulating material. In the insulated wire obtained by heat processing, the terminal of the at least 1 molecule is apply | coated to the at least outermost layer which the polyamide resin which is an alkali group of 21 or more carbon atoms as a main component. Heat-treated language paper is insulated wire. In the case of applying solid lubricants such as solid paraffin and kinaba nab on the insulated wires, and adding synthetic resins having excellent lubricity such as solid lubricants, polyethylene, and polypropylene to the insulating paint, The insulated wire of the invention has equivalent lubricity in itself.
본 발명의 절연전선에서는 절연재료 그 자체가 윤활성이 우수한 것이고, 종래와 같이 절연전선의 표면 또는 절연피막속에 윤활제가 존재하는 것이 아니다. 또 단순한 브랜드가 아니므로 피막자체의 강도도 강하고 그 자체로 슬릇예 삽입할 때의 기계적 손상에 충분히 견뎌내는 이점이 있다.In the insulated wire of the present invention, the insulating material itself is excellent in lubricity, and the lubricant is not present on the surface of the insulated wire or in the insulating film as in the prior art. In addition, since it is not a simple brand, the film itself has a strong strength, and in itself, has the advantage of sufficiently enduring mechanical damage when inserted into a bowl.
따라서 폴리에틸렌, 폴리프로필렌등의 윤활성이 우수한 합성수지를 첨가한 절연도료에서 얻어지는 절연전선에 비해서 외관이 우수한 절연전선이 얻어진다. 또 고형다라핀, 카아나바납 등의 고체 윤활제를 절연전선의 표면에 도포한 것 또는 이들 고체 윤활제를 절연도료 속에 첨가해서 얻어지는 것과 비교해서 냉매. 용제등에 의한 추출물도 적고, 콤프레서의 밸브나 노즐등에서 막히는 염려도 없고, 내냉매성이 요구되는 냉동기 모우터 등에의 적용이 가능하다.As a result, an insulated wire having an excellent appearance can be obtained as compared with an insulated wire obtained from an insulating paint containing a synthetic resin having excellent lubricity such as polyethylene and polypropylene. Moreover, a refrigerant | coolant compared with what is obtained by apply | coating solid lubricants, such as solid dalafin and a carnauba wax, on the surface of an insulated wire, or adding these solid lubricants into an insulating paint. There are few extracts by solvents and the like, and there is no fear of clogging with a compressor valve or nozzle, and the present invention can be applied to a refrigerator motor or the like requiring refrigerant resistance.
본 발명에서는 적어도 한개의 분자의 말단이 탄소수 21이상의 직쇄 알킬기인 폴리아미드이미드를 주성분으로 하는 도료를 절절 연전선의 적어도 최외층을 구성하도록 도포, 열처리할 필요가 있다. 적어도 최외층에 도포, 열처리를 하지 아니하면 본 발명의 목적으로하는 우수한 윤활성을 가지는 절연전선을 얻을 수 없기 때문이다. 본 발명에서 사용하는 도료는 도체상에 직접 또는 다른 절연물을 개재해서 도포, 열처리한다.In this invention, it is necessary to apply | coat and heat-process the paint which has a polyamideimide whose main terminal of at least one molecule is a C21 or more linear alkyl group as a main component so that at least an outermost layer of a nodular strand may be comprised. This is because an insulated wire having excellent lubricity for the purpose of the present invention cannot be obtained unless at least the outermost layer is coated and heat treated. The coating material used by this invention is apply | coated and heat-processed on a conductor directly or through another insulator.
도포, 열처리해서 얻어지는 수지 피막은 엷어도 대단히 우수한 윤활성을 나타내기 때문에 특히 윤활성이 빈약한 다른 절연물 위에 도포. 열처리해서 보호층으로 활용하는 것이 효과적이다. 다른 절연물로서는 어떠한것도 좋고, 예를들면 폴리우레탄, 폴리비닐포르말, 폴리에스테르, 폴리에스테르이미드, 폴리히단트인, 폴리아미드이미드, 폴리에스테르아미드이미드, 폴리히단트인에스테르, 폴리에스테르아미드 등이 있다. 본 발명의 결연전선을 냉동기 모우터등의 분야에의 적용을 고려 했을 경우 이들 각종류의 절연물중에서도 내냉매용의 절연전선의 절연물로서 사용되는 폴리에스테르, 폴리에스테르이미드 폴리에스테르아미드이미드를 사용하는 것이 바람직하다.Since the resin film obtained by coating and heat treatment shows very good lubricity even if it is thin, it is especially applied on other insulators with poor lubricity. It is effective to use heat treatment as a protective layer. Any other insulator may be used, and examples thereof include polyurethane, polyvinyl formal, polyester, polyester imide, polyhydrant, polyamideimide, polyesteramideimide, polyhydrant inester, and polyesteramide. When considering the application of the bonded wire of the present invention to fields such as a refrigerator motor, it is preferable to use polyester, polyesterimide, polyester amideimide which is used as an insulator of insulated wire for refrigeration, among these various kinds of insulators. desirable.

폴리아미드수지에 점하는 말단의 직쇄 알킬기의 비율이 0.3중량% 미만인 경우에는 윤활성이 빈약하고 3.5중량%보다 커지면 도료로서의 저장안정성, 또 전선으로서의 외관 및 기계적 특성에 악영향을 준다. 이 벙위중에서도 도료로서의 저장안정성, 또 전선으로서의 외관의 점에서 더욱 호적하기로는 폴리아미드 수지에 점하는 말단의 직쇄 알킬기의 비율이 0.3∼2.5%중량의 범위에 있어야 한다.If the proportion of the terminal straight chain alkyl group on the polyamide resin is less than 0.3% by weight, poor lubricity and greater than 3.5% by weight adversely affect the storage stability as a paint and the appearance and mechanical properties as an electric wire. Among these, the ratio of the linear alkyl group at the terminal to the polyamide resin should be in the range of 0.3 to 2.5% by weight in order to be more suitable in terms of storage stability as paint and appearance as electric wire.

If the reaction is insufficient, a polymer solution having a straight chain alkyl group of 21 carbons or more remains unreacted in the solution, and this unreacted product lacks compatibility with the polyamide resin and also has poor solubility in phenolic solvents. This unevenness and turbidity may result in gelation, and the resulting electric wire may be unlubricated, which may adversely affect its appearance. In order to fully advance reaction, it is good to carry out for a long time at high temperature as possible. As temperature which advances reaction, 150 degreeC or more is suitable as a suitable thing, and 180 degreeC or more which is more suitable is preferable. In practice, it is preferable to carry out the reflux temperature of the reaction system in order to shorten the reaction time.
